Optics - 4

The thin lens - a medium bounded by two curved refractive surfaces, the thickness of which is negligible compared to the other parameters.

• True

• False

For spherical surfaces, the distance to the image does not depend on the refractive index of the spherical surface.

• True

• False

In the case of a spherical surface, the radius of the surface must be taken into account during imaging.

• True

• False

When imaging with a spherical surface, it does not matter whether the surface is concave or convex

• True

• False

The biconvex lens is a condenser, converging lens.

• True

• False

The double concave lens is a diverging lens.

• True

• False

In the case of a condensing lens, the image will always be real.

• True

• False

The converging lens always creates a virtual image.

• True

• False

The converging lens creates a virtual image when the subject distance is less than the focal length of the lens.

• True

• False

The 2 cm tall object is 10 cm far in front of a mirror with a radius 16 cm.

Determine the focal length of the mirror if it is a concave one.
